TEHRAN (FNA)- The Iranian foreign ministry warned that Washington cannot be fully trusted in any possible future talks with North Korea as the US has earlier proved its untrustworthiness by violating the 2015 nuclear deal with Tehran.

"If what has been said comes into action, we will welcome talks between the US and North Korea and any efforts to assist establishment of global peace, stability and security," Foreign Ministry Spokesman Bahram Qassemi told reporters in a press conference in Tehran on Wednesday.

"But I should acknowledge that it has been witnessed in practice that the US policies and approaches cannot be trusted so much but steps taken in the direction of peace and stability in the world are welcomed by Iran," he added.

South Korea announced earlier this week it has not received a response from Pyongyang on a summit between North Korean leader Kim Jong-un and US President Donald Trump.

In a surprise development, Trump on Friday accepted North Korea's invitation to direct talks.

South Korean officials said Kim was prepared to give up his nuclear weapons.

Details on the planned talks remain vague, with no agreement yet on the location or agenda.

Analysts are skeptical about what can be achieved through talks given the complexity of the issues involved.

"We have not seen nor received an official response from the North Korean regime regarding the North Korea-US summit," a spokesman for the South Korean Ministry of Unification said on Monday.

"I feel they're approaching this matter with caution and they need time to organize their stance."

Some observers believe that North Korea's procrastination to give a response to Trump is due to his disloyalty to the 2015 nuclear deal with Iran, signed during the presidency of Barack Obama.

Iran and the Group 5+1 (the US, Russia, China, Britain and France plus Germany) finalized the nuclear accord in July 2015 and started implementing it in January 2016.

Under the deal, Iran undertook to apply certain limits to its nuclear program in exchange for the termination of all nuclear-related sanctions against Tehran.

Trump on January 12 reluctantly agreed to waive sanctions against Iran that were lifted as part of the landmark deal, but said it would be the last time he issued such a waiver unless conditions were met.

Trump said he wanted Congress and America's European allies to use the 120-day period before sanctions relief once again comes up for renewal to agree to tougher measures and new conditions; otherwise Washington would pull out of the deal.
